INSTRUMENT FOB SECURING CONCAVE METAL STOPPERS IN BARRELS.

To all whom it may concern: Be it known that I, JOSEPH GALLEAZZI, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Instruments for Securing Concave Metal Stoppers in Barrels or the like, of which the following is a specification;

The object of the present invention is to provide a device for closing openings through barrels, such as cement barrels,.by means of a metallic sheet metal stopper.

In the accompanying drawing, Figure 1 is a central vertical section showing my device in position for operation, certain parts being shown in side elevation; Fig. 2 is a similar view showing the device in operation, and certain parts being shown in positions different from those in Fig. 1; Figs. 3 and 4 are horizontal sections thereof in the positions shown in'Figs. 1 and 2 respectively; Figs. 5 and 6 are bottom plan views of my improved device in the same positions as shown in Figs. 1 and 2 respectively.

Referring to the drawing, 1 indicates an end of the barrel in which is a hole- 2 adapted to be closed by a concave stopper 8, shaped from sheet metal into a cylindrical pan-shaped form. These stoppers are not, as a rule, of the exact size necessary to make a tight fit in the hole. It is the object of my invention to provide a device which will render them practicable to be used as stoppers notwithstanding their loose fit.

This device comprises a shaft 4 which ex- 7 tends upwardly through a tube or bushing 5 and through a central hole in a circular disk 6, said shaft being supported in the disk. A bearing block 7 surrounds this bushng and is rotatable on the shaft. A tube 8 surrounds the shaft 4 and on the upper end thereof is a crank arm 9, having a handle 11 on its free end. The tube 8 is secured to said shaft by a set screw 42.

Said bearing block is formed with bearings 12 fora shaft 13, on which is pivotally mounted a lever 14, of which the long arm 16 forms a handle, while the short arm 17 extends into a slot 18 in a loop-shaped slide piece 19 having rounded ends and sliding in a horizontal guideway 20 in said block. In the center of the front end of said loopshaped slide piece is secured an outwardly extending punch 21.

The disk 6 is of such size as to just fit Specification of Letters Patent.

Patented Apr. 27, 1920.

Application filed May: 13, 1919. Serial No. 296,729.

ter has been placed in position, and the disk 6 has been so fitted, downward pressure is applied to the handle 16 of the lever 14, forcing the punch through the side of the sheet metal stopper, making a round hole therein, and a socket in the adjacent wall of the hole 2 in the end 1 of the barrel, and forcing the edge of the sheet metal stopper around the hole thus formed into the socket in the wall in the end of the barrel. The punch being then withdrawn, the bearing block may be turned on the tube 5, and the operation of so securing the sheet metal to the wall of the hole in the barrel may be repeated in another location, and so on as often as may be thought necessary, thus securing the stopper in the hole in the barrel.

On the lower end of the shaft 4 is secured a cross piece 22 having rounded ends which are received in rounded cavities in the inner ends of dies 23 movable in a groove 24 in the under side of the disk 6, and pivotally secured, as shown at 25, to said disk. The outer ends of said dies converge to form narrow rounded ends. In one position of the cross piece 22, as shown at Fig. 5, the outer ends of said dies are entirely withdrawn into the groove 24 in the under side of said disk 6 so that; they do not obstruct the disk when being lowered into the concave stopper 3, but when, by turning the handle 11 in a left-handed direction, the

said dies gradually outward. As they moveoutward, they press against the inner surface of the stopper at its'inner end. Said stopper extends not only entirely through the hole in the end of the barrel but also to a distance within the barrel not less than the thickness of the dies. Thus the dies gradually swage outward said inner end until a straight edge 26 of each die contacts with a wall of the groove; so that a circular hollow flange 27 is formed thereon, as shown at Fig. 2, thereby tightly closing the stopper against the end wall of the barrel and preventing the escape of the pulverized material from the barrel through the hole 2.

I claim 1. In a device for securing a hollow stopper in a hole in a wall of a container, the combination of a disk adapted to be received within the stopper, a die pivotally supported on the under side of said disk per in a hole in a wall of a container, the,

combination of a disk adapted to fit within the stopper, a die pivot-ally supported on the under side of said disk and adapted, in one position, to extend beyond the disk, and, in another position, to be withdrawn Within the periphery of said disk, a shaft extending through the disk, an arm secured to the shaft on the same side of the disk as the die and having an operative connection with an end of the die to turn the same from one to the other of the said positions, and means for turning said shaft.

3. In a device for securing a hollow stopper in a hole in a wall of a container, the combination of a disk adapted to fit within the stopper, dies pivotally supported on the under side of said disk, and adapted in'one position to extend beyond the disk and i1? another position, to be withdrawn within the periphery of said disk, a shaft extending through the disk, a cross arm secured to the shaft on the same side of the disk as the dies and having operativeconnections with ends of the dies to turn the same from one to the other of the said positions, and means for turning said shaft. f

4:. In a device for securing a hollow stopper in a hole in a wall of a container, the combination of a disk adapted to be received within the stopper, a bearing rotatably supported upon said disk, a suitably guided lever pivotally supported by said bearing-,1,

a guide piece operatively connected with said lever to be moved thereby toward the wall of said stopper, and a punch carried by said guide piece. I r V 5. A device for securing a hollow stopper in a hole in a wall of a container, a disk adapted to be rotatably received in said hollow stopper, a die mounted upon said disk for movement to extend beyond the periphery of the disk, means for extending said die through which means the disk may be rotated when the die is extended, a punch mounted upon the disk and arranged to penetrate the sides of the stopper and means for operating said punch.
